This game is awesome!
The different stages you can play when attempting to find all of the particles are really unique and fun. Also, the minimalist graphics really add a nice touch to the game. The audio and music are really cool and fit with the theme of the game. The ending was also really cool. Finally, this game is about SCIENCE. Particle physics are awesome, man.

Though, I do have a little to say on the more negative side. I liked how there was (sort-of) a story line, but I really thought it could've gone more in-depth with everything. Maybe some intro that actually shows how Erik and Niva got themselves into this type of situation, and also how they don't die after the collisions. I also think the game should've explained what happened to Erik and Niva after they finally discovered all of the particles, X Boson included.

All in all, this is a really cool game, though there's some room for improvement on the story of the game.
